  1. 1. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Mineur; [2023]
    Nyckelord :Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

    Sammanfattning : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. LÄS MER

  3. 2. Efficient FE Modeling of Large Casted Parts

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Nyckelord :FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Sammanfattning : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. LÄS MER

  4. 3. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Isabelle Löfgren; [2022]
    Nyckelord :impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Sammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER

  5. 4. Simulation of a Battery Energy Storage System for Fast Frequency Reserve Support.

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pathirage Dona Upekha Nimanthi Pathirage; [2022]
    Nyckelord :Energy Storage; Renewable Energy; Battery; Fast Frequency Reserve; Lithium-ion;

    Sammanfattning : Electricity providers has a growing interest in moving towards Renewable Energy Sources (RES) for power generation due to their attractive features. This has caused phasing out of coal, oil and nuclear power plants which use large synchronous generators for power production. LÄS MER

  7. 5. Laser Arc Hybrid Welding of Thicker 6000-series Aluminium Alloy : Laser-MIG butt welding of 8 mm 6082-t6

    Master-uppsats, KTH/Industriell produktion

    Författare :Björn Lindeberg Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : Laser arc hybrid welding presents many benefits but has many parameters that must be optimised for it to work. It becomes even more challenging when welding thicker aluminium with the process. Welding of thicker aluminium alloys involves a lot of different challenges, on itself. LÄS MER
